Sex differences in complex traits are suspected to be in part due to widespread gene-by-sex
interactions (GxSex), but empirical evidence has been elusive. Here, we infer the mixture of …

The recent increase in available molecular and genomic data for diverse taxa helps to shed
new light on long-standing theories. Research into sex chromosome evolution has …

Diadromy, the predictable movements of individuals between marine and freshwater
environments, is biogeographically and phylogenetically widespread across fishes. Thus …

Intralocus sexually antagonistic selection occurs when an allele is beneficial to one sex but
detrimental to the other. This form of selection is thought to be key to the evolution of sex …

How consistent are the evolutionary trajectories of sex chromosomes shortly after they form?
Insights into the evolution of recombination, differentiation, and degeneration can be …

Sexually antagonistic (SA) genetic variation—in which alleles favored in one sex are
disfavored in the other—is predicted to be common and has been documented in several …

Sex-differential selection (SDS), which occurs when the fitness effects of alleles differ
between males and females, can have profound impacts on the maintenance of genetic …

Females and males carry nearly identical genomes, which can constrain the evolution of
sexual dimorphism and generate conditions that are favourable for maintaining sexually …

Recent methodological approaches have expanded our understanding of Y chromosome
sequence, revealed unexpected Y diversity, and sparked a growing realization of its …

Sex differences in the fitness effects of genetic variants can influence the rate of adaptation
and the maintenance of genetic variation. For example,“sexually antagonistic”(SA) variants …
